The greatest collection of negative e-mail I have ever received came in response to the ending of Creative Composition. Surprisingly, some people actually agreed with the way the story ended, overwhelmingly, most people felt the ending was rushed or incomplete. A lot of people also felt that it's almost impossible to disappear in today's world -- it's not, as long as you stay away from social media, and don't advertise yourself.
That being said, I have done something that I was rather loathe to consider until a voice started yelling in my head. As a result, I have extended the last chapter of the story. I have not changed a single word that was there before. I have simply added a few hundred more.
The changed chapter is queued for publication. I'll be interested in opinions.
